J & W GH6250Y MANUAL LATHES

Technical Description

The J & W GH6250Y is a manual engine lathe designed for general-purpose turning operations in small to medium-sized machine shops. This lathe features a 500mm (19.69-inch) swing over bed, allowing operators to machine workpieces up to this diameter. The spindle bore measures 3.15 inches, providing adequate clearance for bar stock and accommodating various cutting tool configurations. Operating at a maximum spindle speed of 1,600 RPM, the lathe delivers controlled rotational performance suitable for precision turning, threading, and facing operations on ferrous and non-ferrous materials. The swing over cross slide is rated at 300mm (11.81 inches), enabling access to internal features and stepped diameters without obstruction from the toolpost assembly. The machine offers multiple center distances—1,000mm, 1,500mm, 2,000mm, and 3,000mm—providing flexibility for machining components of varying lengths. The gap width of 710mm allows for the accommodation of larger diameter workpieces by partially retracting the gap section beneath the spindle centerline. As a manual lathe, the GH6250Y requires skilled operator input for all movements and feed rates, making it ideal for experienced machinists performing custom and small-batch work. Built by Nanjing J & W Manufacturing, this machine represents a reliable choice for shops requiring durable, straightforward turning capabilities without automated features, offering excellent value for foundational metalworking applications.
